About

A simulator aim at simulating and solving Transmon based qubit-coupler-resonator system.

This program is directed by Dr. Fei Yan, BAQIS. The original code structe is adoppted from Mr. Pan Shi, Wuhan University & BAQIS, and contributed by Mr. Jiheng Duan and Dr. Ruixia Wang, and Dr. Zhen Chen.

Look up the PyPI page: https://pypi.org/project/qusim/

User_Guide

Install (use pip)

pip install qusim

Requirement

You are required to install all these python packages in the system for running this simulator. See requirements.txt.

• Python, version >= 3.10

Installing virtual environment using conda conda -n env_name python=python_ver -ipython

• qutip, version >= 4.6.3

• Nocie that qutip 4.6.3 requires scipy 1.10.1 exactly. Otherwise it will raise up error in function fast_crs_matrix. (https://stackoverflow.com/questions/76560698/python-3-10-qutip-attributeerror-cant-set-attribute-format)

• matplotlib==3.8.3
• mpmath==1.3.0,
• pillow==10.2.0,
• scipy==1.12.0,
• sympy==1.12,
• tqdm==4.66.2,
• h5py==3.11.0,
• pyqtgraph==0.13.7,
• PyQt5==5.15.10,
• vispy==0.14.3,
• jupyter lab or jupyter notebook, optional

Download

Just downloading the entire folder.

There is also a release.

Usage

We have two version: the transmon_system.py and arb_qubit_system.py

The detailed tutorial are shown in folder tutorial/~, including required imports, define a system, what inside a system, scan zz-coupling, scan energy level, driven system dynamics, single qubit gate calibration, and DRAG calibration.

Features

Our simulator includes the following features:

• Support multiple qubits
• Multiple initial state simulation
• Internal plot function
• DRAG
• Generalized for any qubit
• Good data saving and loading functions
• Tunable coupler helper
• Aviod crossing helper

ToDoList

Stop lazying

               ---------Runaway_Fancy

• Pulse sequence compiler
• A better gate set paramter management system
• Bentchmakring tool box
• State/process/gate set tomography tool box
